To loosen 2 glasses stuck together, don't panic!
Rather than tugging at them like a brute and risking breaking them, there is a very simple trick.
The trick is to use hot and cold water to loosen them effortlessly:
1. Put cold water in the top one. The colder, the better. You can use ice cubes to cool the water if needed.
2. Then place the bottom glass in a bowl of hot water. The hotter, the better. If you don't have a bowl, you can put it directly in the sink.
3. Wait 1 min and unjam the 2 glasses.
There you go, your glasses are unstuck :-)
